Compiler Flags in first line of program

[Motu]

it would be sometime usefull if you could place compilerflags in top of the program, because sometimes different programm version require different compilersetting:

compilerif NeedThreadSafty = 1
#PB_Compiler_Thread = 1
compilerelse
#PB_Compiler_Thread = 0
compilerend

Sometink like this

Huh? That's up to the programmer, not PureBasic.
